Abstract
Background: Nowadays, the optimal surgical margin of the resected metastasis and the parenchyma sparing surgical technic have become an issue among hepatic surgeons. Some authors suggest performing parenchyma sparing surgery as the best surgical strategy for colorectal liver metastases (CLRM) to keep as much liver tissue as possible. Furthermore, the microscopically positive surgical margin (R1 resection) is presumed not have worse survival outcomes compared to patients with microscopically negative surgical margin (R0 resection).
